CENTRiFUGAL PUM P.

SPECFICATION forming part of Letters Patent No. 569,655, dated October 20, 1896.

Application filed November 24, 1894. vSerial No. 529,843A (No model.)

To ctZ whom t may concer/1,.-

Be it known that I, CHARLES MCINTYEE, of Fort Benton, in the county of Choteau and State of Montana, have invented certain new and useful Improvements in Centrifugal Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in centrifugal pumps, having reference more particularly to the specific form known as force-pumps.

rlhe object of the invention is to provide simple and highly efficient means for effecting the discharge of the water at the periphery of a wheel in such manner that the force of the discharged water will be fully utilized and aid in revolving said wheel.

A further object is to provide simple and efficient means for directing the iiow of dis charged water from the periphery of the wheel.

To these ends the invention consists,prima rily, of a hollow wheel provided with a series of divergent guides for directing the passage of the water toward the outlets at the pcriphery of said wheel.

The invention further consists of a hollow wheel provided with a series of divergent guide-plates having outer angular ends adjacent to the discharge-openings in the top of said wheel, and series of nozzles or elbows extending from. said discharge-openings.

The invention further consists of a hollow wheel having angular discharge nozzles or elbows and a series of divergent guide-plates located in said wheel and extending to said nozzles, and a circular series of buckets surrounding said wheel on a line with said nozzles, said buckets being supported by arms connected to the hub or center ofsaid wheel.

The invention also comprises the details of construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and partieularlypointed out in the claims.

In the accompanying drawings, Figure lis a vertical sectional view illustrating my iinprovements. Fig. 2 is a plan view thereof with the top of the air-tight casing or cylinder broken away and some of the buckets omitted.

Referring to the drawings, A designates a wheel which is made hollow and inclines upwardly from its center to its periphery. This wheel is composed of parallel top and bottom plates or disks a a', connected together at their outer edges.v In the top plate a are formed at periodical distances apart holes or openings in which fit the inner ends of nozzles or elbows o?, which are bent or curved so that their outer ends are on a line with the wheels periphery. Vithin this wheel are arranged guide-plates B, which diverge from the hub or center of the wheel to near the periphery thereof, the end of each plate being on one side of each of the outlet-openings, and from each of these plates, from a point near the end thereof, projects a right-angular branch plate l), which extends beyond and incloses one side of the outletopening, the end of said branch plate extending to the periphery of the wheel. These guid e-plates, together with their rightangular branches, direct the flow of the water in the hollow wheel to the outlet-openings thereof, whereby the same will be discharged through the nozzles or elbows.

The wheel A is provided with a central cylindrical sleeve d and an outer shorter depending extension cl', which fits in a casing cl2, beneath the bell-mouth Z3 thereof, said casing being attached to the bottom of an inclosing air-tight cylinder C and provided with a tubular portion d4, through which the water is drawn. The sleeve d fits snug in a central stationary tubular bearing d5, extending upwardly in casing (Z2, and in this sleeve cl fits a shaft D, which extends up beyond wheel A, its lower end being proj eeted beneath the cylinder O and resting upon a base d. Upon this shaft is a sheave-wheel d?, while upon the lower projecting portion of sleeve d is a second sheave-wheel ds, and beneath the latter is a box (Z9, which rests upouball-bearings dw, iitted in a groove of wheel d. Upon the upper end of shaft D is keyed a hub or sleeve (1,12, having a central horizontal iange d.

E E are a series of buckets, each of which is of approximately V shape in plan view, with one side longer than the other, and said longer side is provided with aplate or eXtension f, which is made fast to the inner side of a ring F, which is supported by lateral arms f', secured at their inner ends to the ICO broad openings.

charged by wheel A is thus utilized to aid in The primaryk powei` revolving said wheel.

` for revolving the latter is applied to the sheave-wheel d8. This formV of centrifugal pump has many advantages over the formr shown in my pending application for Letters Patent, tiled March 1S, 1892, Serial No. 466,688, and especially in that the wheel is made hollow'and provided with guideplates for directing the water to the youtlctnozzles or elbows. By this means the water is discharged wit-h greater forcethan through hollow arms and the full force of the discharged water is received by the buckets and by them imparted to the wheel, thus aiding in revolvingV the latter and rendering lessV primary power necessary.

The water discharged by wheelA can be stored in cylinder C, and under air-pressure therein Vcan be forced therefrom and further utilized.

The advantages of my invention are apparent to those skilled in the art to whichit appertains, and it will be specially observed that by the form of the wheel described the full centrifugal force of the water is obtained, and byreason of the nozzles or elbows the water is discharged with great force against the buckets, which are in close juxtaposition thereto, and hence the force of the discharged water is utilized in aiding in turning the hollow wheel.

I claim as my inventionl. In a centrifugal pump, a hollow rotary wheel having discharge-openings adjacent to its periphery, nozzles or elbows iitted in said openings, and divergent guide-plates within said wheel extending from the center to near the periphery thereof and having angular branches inclosing said discharge-openings, substantially as set forth.

2. In a centrifugal pump, a hollow rotary wheel composed of upper and lower plates or disks connected together at their edges, said upper plate having openings therein, nozzles or elbows fitted in said openings and having their outer ends on a line with the periphery of the wheel, and the series of guide-plates located within the wheel and extended from the center to near the periphery thereof on one side of each of said openings and having each a right-angular branch extending over the other side of such opening, substantially as set forth.

3. In a centrifugal pump, a rotary wheel having its inlet at its center and its discharge on a line with its periphery, said wheel being inclined upward from its center outward and made hollow and provided with a series of radial guides diverging from the center to its points of discharge for directing the flow or' the water, said guides being provided with outer angular branches, substantially as set forth.

4. The combination of the hollow rotary wheel having a central inlet-opening, a depending cylindrical extension, discharge nozzles or elbows,.radial guide-plates located in said wheel and extending from its center tok said discharge nozzles or elbows, the casing in which said cylindrical extension fits, having afccntral sleeve,and the shaft'iitted in said sleeve and supporting said wheel, substantially as set forth.

5. In a centrifugal pump, a hollow rotary wheel having a lower cylindrical extension and a depending supporting-sleeve within said extension, discharge-nozzles secured in the top of said wheel adjacent the periphery thereof, a casing in which. the cylindrical extension of said wheel fits, a rotary shaft extended through said central sleeve, the series of buckets surrounding said wheehthe ring carrying the same supported by said shaft, and the arms connected to said ring and also to said shaft, substantially as set forth.

6. In a centrifugal pump, a hollow rotary wheel having a lower cylindrical extension and a depending supporting-sleeve within said extension, discharge-nozzles secured in the top'of said wheel adjacent the periphery thereof, a casing having a sleeve therein in which said central sleeve fits, a rotary shaft extended through said central sleeve, a bearing-box for the lower end of said central sleeve, the circular series of buckets surrounding said wheel, a ring carrying the saine, a hub keyed on said shaft, and arms connected to said hub and said ring, substantially as set forth.

7. In a centrifugal pump, a hollow rotary wheel having a lower cylindrical extension and a depending supporting-sleeve within said extension, discharge-nozzles secured in the top of said wheel adjacent the periphery thereof,-ar casing in which the cylindrical extension of said wheel fits, a rotary shaft extended through said central sleeve, the circular series of buckets each of which is of approximately V shape open at their wide ends and having extensions on one side, the ring carrying the saine supported by said shaft, and the arms connected to said ring and also to said shaft, substantially as set forth.
